SPECIFICATION forming part of Letters'Patent No. 556,677', dated March 17, 1896. Application filed September 30, 1895. Serial No. 564,092. (No model.)

To au whom, it may concern: the form of a cylinder or barrel S, which is Bc it known that I, CHARLES T. JENNE circular in cross-section.

MANN, of the city of St. Louis, in the State of Sindicatos awaste or drain opening formed 5 Missouri, have invented certain new and usein the wall of the cylinder S, adjacent the up 5 ful Improvements in I-lydrants, of which the per end thereof.

A stem 2i passes ver- 5 with the space above said partition. The tically through the cap 23 and is provided space above said partition is preferably in with an operating-handle 25 on its upper end.

Upon the lower end of said stem is formed a sere w-thread 2G that operates in the upper end of a short tube 27, the same being screwed onto the upper end of the removable tube or pipe 12. The short tube 27 operates vertically in guides 28, formed integral with the interior of the casing 22. Formed in the short tube 27 adjacent its lower end is an aperture 29.

Protruding from the exterior of the casing 22 is a discharge-nozzle 30. The hydrant-casing of which I make use is constructed in two mating semicireular shells 31, the same having formed integral with their lower ends mating base portions 32, from which depend 'flanges 33, that meet and are held together b y bolts 34. The upper end of the casing is slightly smaller in diameter than is the lower end, and formed integral with said upper end is a bead having a beveled face 36. A ring 37 is constructed with an interiorly-beveled face 38, that engages directly upon the beveled face 36, formed on t-he upper ends of the mating portions of the casing when the various parts are properly put together.

VWhen the upper end of the shell 1 is screwed into the lower end of the casing 22, said lower en d of the casing rests directly upon the top face of the ring 37 and causes the same to bear on the beveled faces formed on the upper ends of the mating portions of the hydrant-casing, thus firmly holding said mating portions together and doing away with the necessity of bolting the upper ends of the seinicircular portions of the easing together.

The operation is as follows: The normal position of the parts is that shown in Figs. l and 6, in which the valve 18 is closed upon its seat and the nut 19 is located in the passage 7 and with the pipe 12 and all parts earried thereby at the limit of their downward movement. lVhen the parts are in this position, the cup 16 engages the interior of the cylinder 8 at a point beneath the upper end of the waste-port 11 and above the lower end of said port, so that said valve 1S prevents inlet of liquid by way of the supply connection 3, and the waste liquid from the pipe12 gravitates downward therein, passes out through the water-passage and enters the cylinder at a point below said cup, thence passes into the waste-port 11, thence out of the upper endof said port into the cylinder at a point above said cup, and thence makes its exit by way of the waste-opening 9, so that all possible injury to the hydrant by freezing is obviated.

In Fig. 7 I have shown the valve in an open position, and when the same is in said position there is a free passage for fluid from the inlet connection 3 upward through the passage 7 to the interior of the cylinder S, through the water-passage 2O in the head let and to the interior of the pipe 12. From the pipe 12 the water passes into the short tube 27, located on the upper end thereof, and trom thence makes its exit through the apertures 29, and from thence through the discharge-nozzle 30. extending laterally from the casing 22.

Vhen the valve is opened, which is brought about by simply turning the handle a number of times to the left, it will be observed that the head lat and all parts carried there by simultaneously move upward with said pipe and the cup 1G slides over and covers the up per end of the outlet 11, preventing outiiow of liquid therefrom. Said cup forming a tight joint with the interior of said cylinder also prevents passage of any liquid upward into the annular space surrounding said pipe l2.

By constructing the hydrant-casing in mating portions the same is very easily and expeditiously put together or taken apart, and by providing the form of ring shown kin Fig. 4c and hereinbefore described the necessity of bolting the mating portions of said casing together at the top is obviated.

A hydrant of my improved construction possesses superior advantages in point of simplicity, durability and general elliciency, 1s easily constructed and put together, and may be quickly taken apart when in need of repairs.

I claim- In combination with a tubular hydrant, a casing constructed in mating portions arranged to inelose that portion of said hydrant that is aboveground, bolts securing the lower ends of the mating portions together, and a ring that is engaged by a .portion of the hydrant-tube to securely lock the upper ends of the mating portions of the casing together.

In testimony whereof I affix my signature in presence of two witnesses.
